| Abstract: | To avoid the premature problem and the slow convergence of simple genetic algorithm(SGA),an improved adaptive genetic algorithm was presented to used for determining molecular formulas of organic compounds.The improved adaptive genetic algorithm was proposed on the basic of the existing adaptive genetic algorithm to improve the coding modes,genetic operators,etc.The algorithm ap- plied to determine molecular formulas of organic compounds were much better than those of SGA. |
